Study Notes
Delayed Type Hypersensitivity Reaction
- Activated T-lymphocytes produce effector cytokines interferon gamma (IFN-ϒ) and tumor necrosis factor-alpha (TNF-α) in response to infection.
- These cytokines attract a large number of different cells, including macrophages, lymphoid cells, granulocytes, and others, from capillaries to the site of infection.
- The attracted cells play a crucial role in the formation of granulomas, which helps to limit the spread of Mycobacterium tuberculosis in the body.
